The Thermal Shock Chambers from Giant Force Co. Ltd. – Taiwan are technically superior and at par with any reputed brands in the World but at a very reasonable price.  They are supplied either in 2 zone or 3 zone Models and each chamber is divided into 3 sections of a High temperature compartment, a low temperature and the Testing compartment and are supplied with internal chamber volume from 50 litres up to 300 litres.  The sub-zero temperatures of these chambers can be selected using optional CO2 or LN2 cooling system. The Chambers has a very advanced colour touch panel control system with a memory capacity for storing up to 120 programmes and can be connected to a PC and all the test data can be down loaded for documentation. These Chambers has many advanced as well as safety features like automatic shut down and warning sign if any mal-functions are encounted by the PLC.

With 150mm X-Y stages and an adjustable height clearance of up to 200mm, the ST400 is ideal for a wide range of samples with varied geometries. With the optical video zoom or optical microscope, high magnification microscopy work can be done in combination with measuring roughness and other properties at precisely selected locations. An AFM integration expands the 3D capabilities into the sub nanometer range including laterally which is not attainable with any other optical technique. The advanced software makes it easy to select zones on the video to be scanned automatically by Profilometer or by the AFM. Quality control options are available to automate various aspects of testing including image pattern recognition, database communications, macros for automatic testing and analysis recipes. Chromatic Confocal line sensors are also available on this system to allow speed of up to 200 times faster than the single point sensor. Custom ST400’s are available for more open configurations that allow for larger X-Y stages, 360° rotational stages and many other custom configurations. The Chromatic Confocal technique uses a white light source (LED) that passes through a series of lenses, called an optical pen, which has a high degree of chromatic aberration. The refractive index of the lenses will vary the focal distance of each wavelength of the white light. In effect, each separate wavelength of the white light will focus at a different distance from the optical pen, creating the measurement range. When a surface of interest is within the measurement range a single wavelength of the white light will be in focus while all others will be out of focus. The white light is then reflected back through the optical pen, then through a pin hole filter that allows only the focused wavelength to pass through to a CCD spectrometer. The CCD will indicate the wavelength in focus, which corresponds to a specific distance for a single point. The physical wavelength measured uses no algorithms providing the highest accuracy independent of form, roughness level, illumination and measurement speed. There is no special levelling procedure required. And while others make claims of resolutions Nanovea provides high accuracy.• Physical Wavelength Measured + No Algorithms Needed for Results = Higher Accuracy• Level of accuracy independent of form, roughness level, illumination and measurement speed• No special levelling procedure required• Most claim very high resolutions. Nanovea provides high accuracy. CHROMATIC CONFOCAL MEASUREMENT Chromatic Confocal by design ensures the highest accuracy of all optical techniques. Specifically when measuring surfaces that are geometrically complex (randomly rough surfaces). Other techniques are subject to many error sources that are simultaneously present and it is not possible to remove or compensate for them or even to estimate their combined influences. The Profilometer offer high accuracy across the widest range of materials and surfaces conditions including tissues, biomaterials, polymers, plastics, metals, composites and ceramics. As an additional measurement signal to the height data, the technique also provides reflection intensity which can be used for highlighting features not seen by height variations.  It can also be used to quantitatively measure variation of surface reflectivity.

A range of 6 saturated humidity and salt spray cabinets. Two sizes, with either 500 or 1000 Litre internal capacities (16.6 / 35.3 cu ft). Robust glass reinforced plastic (GRP) construction, a durable impact resistant material with strong chemical and corrosion resistant properties to ensure a long life. Fully transparent and seamless domed roof providing 360° visibility, self-supporting when open. Key Features Precise temperature controlled, high humidity environment. Water held in a sump located in the cabinet base, is heated by an immersion heater to generate water vapour. As water vapour evaporates, it saturates the cabinet atmosphere with moisture. Test samples in the cabinet, below the dew-point temperature of the saturated air, will develop surface condensation. By careful design the high humidity environment is achieved without the need for a circulation fan, which would otherwise have to endure the hostile, high humidity environment. Safety cut-outs ensure the immersion heater is automatically isolated if the water reservoir runs dry.

Functionality of a product is considered as a matter  of course, so the perception of quality is determinedprimarily by the visual appearance. Damage to a surface by the human hand is one of the main reason for disturbance of the products quality perception. The hand abrasion is a very complex chemical and mechanical combination. By touching a surface the human hand performs a mechanical strike followed by a push-slide force. The human hand consists of a visco elastic material containing a rough and structured surface. In addition, sweat or hand cream creates a severe chemical environment.   TRIBOTOUCH The TRIBOTOUCH instrument is designed to do real life testing of finished products or lab samples in regards of resistance to hand abrasion. The set-up of the TRIBOTOUCH is exactly reproducing the complex chemo mechanical system of the human hand abrasion according to international standards. The flexible design of the TRIBOTOUCH allows various options and delivers reproducible results.
